I would suggest attending your local real estate meetups, Joining a group and educating yourself while repairing your financial situation. 

I am a newbie investor looking for networking events on the weekends in the NY, NJ areas.

I would make a small commission on such transactions, adding another revenue stream to my portfolio as well as being given the opportunity to invest in said properties in the event of a flip. 

(J) "Disabled licensee" means a person licensed pursuant to this chapter who is under a severe disability which is of such a nature as to prevent the person from being able to attend any instruction lasting at least three hours in duration.

There is also a fantastic networking group in Chicago that does monthly events with panel speakers and all kinds of great intel spanning a variety of topic matters that change each time. 

there is a local real estate networking event here just about every week.

I attended many local REIA meetings and property tours which inevitably helped me visualize. 

Looking for a seminar or other event around the first weekend of April 2019.
